Function Documentation

addSeeds()

void alexaClientSDK::avsCommon::utils::uuidGeneration::addSeeds

(

const std::vector< uint32_t > &

seeds

)

Allows caller to add extra seeds to generate uuid. Good seeds should be random values, such as the time between two consecutive user interactions. UUIDGeneration uses one random_device value, lower 32bits of current time, time between two invocations, and lower 32bits memory address of temporary variable to feed seeds for random number generator.

Parameters

seeds

extra seeds from a random source.

generateUUID()

const std::string alexaClientSDK::avsCommon::utils::uuidGeneration::generateUUID

(

)

Generates a variant 1, version 4 universally unique identifier (UUID) consisting of 32 hexadecimal digits. The UUID generated is of the format xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx where M indicates the version, and the two most significant bits of N indicates the variant. M is 0100 (binary) for version 4 and N is 10xx(binary) for variant 1.

Returns

A uuid as a string.

setEntropyReader()

void alexaClientSDK::avsCommon::utils::uuidGeneration::setEntropyReader

(

std::function< double(void)>

func

)

Set the customized function to read entropy value instead of the default.

Parameters

func	Customized function used to read entropy value.

setSalt()

void alexaClientSDK::avsCommon::utils::uuidGeneration::setSalt

(

const std::string &

newSalt

)

Allows caller to set a specific salt to be used in any seeding operation. Salt wil be a prefix to the seed and should be as specific to the unique device as possible. Setting a salt will cause the next UUID to be generated with a new seed.

Parameters

newSalt

the salt to use
